Click Through Transparent Background

Hi there,

I am trying to use the docking as overlay to my existing WPF application.

I did set the background of the docking to transparent, but I can not click on the items behind it.

If I set ishittestvisible to false then I can click on the items behind the but I can not click on any item in the docking panes anymore.

Is there any trick to archieve this.

My goal is to have a streched docking over my entire application in order to bring in tools from all sides while being able to interact with the underlying grid of controls.

Any hint would be appreciated.

Unhandled COMException when scrolling through a PDF document

Hello,

We have created a small WPF-application which is used to display PDF-files. Although the application works fine on some machines, on others we get an unhandled COMException when we scroll through the document's pages. The exception is not always thrown on the same page and the size of the document or the speed of scrolling does not seem to have an influence.

The documents we tried to display are not corrupt and can be viewed perfectly with other PDF-viewers. The PDF documents are also quite small (+/- 10 pages).

Below you find the call stack of the exception.

Application: PdfViewer.exe

Framework Version: v4.0.30319

Description: The process was terminated due to an unhandled exception.

Exception Info: System.Runtime.InteropServices.COMException

We've also tried the Telerik demo application and this also shows an exception that not enough storage is available. There's definetely enough memory and disk space available for the application.

Could you please help us solve this issue.

Kind regards.

UpdateLayout when a value (fontsize) changes

Hi,

I'm using a RadTileView and it contains some Textblocks. I have a Combobox above the RadTileView that contains int values for font sizes so that when a combobox selection is made the font size of the Textblocks are updated. When I adjust the window size of the RadTileView (with the mouse) it'll update the views so the new font size fits right. I'd like to update the views whenever the combobox is refreshed so I don't have to resize the window manually to achieve this. Preferably in xaml as the RadTileView is within a DataTemplate and difficult to get to.

If it's any help, the binding the Textblocks use is {Binding Source={StaticResource TVFieldSetsVM}, Path=CommonFontSize}.

Thanks

How do I move the "Add New Record" and form to the bottom

I want to move the "add new Record button" to the bottom becase
a) it's more intutive that way and
b) it sometimes dosn't update and then the new record still appears to be the first record instead of the last which is what it really is.

There is a soltion that changes the control template using something called "<VisualStateManager.VisualStateGroups>" which I can't use because I'm still using visual studio 3.5 not 4.0. I am by no means an expert with wpf yet so I don't even know how to do a control template. Can someone point me in the right direction.

Style of selected items in chart

Hi Telerik Team,

the telerik example Programatically selecting visual items with the new interactivity api in radchart
helped me a lot, because i needed exactly this behaviour, but i have a problem to style the points.

I tried this (with different colors to see what is applied)

telerik:SeriesAppearanceSettings x:Key="BenchmarkAppearance"

Stroke="Wheat"

StrokeThickness="2"

Fill="DarkBlue">

<telerik:SeriesAppearanceSettings.PointMark>

<telerik:PointMarkAppearanceSettings Shape="Circle" Stroke="White" StrokeThickness="1"

Fill="Gray"/>

</telerik:SeriesAppearanceSettings.PointMark>

</telerik:SeriesAppearanceSettings>

and this

<Style x:Key="BenchmarkPointStyle" TargetType="telerik:PointMark">

<Setter Property="Shape"

Value="Circle" />

<Setter Property="Stroke"

Value="White" />

<Setter Property="StrokeThickness"

Value="1" />

<Setter Property="Fill"

Value="Yellow" />

</Style>

and this one from the help file RadControls Wpf

LineSeriesDefinition l = new LineSeriesDefinition();

l.Appearance.PointMark.Stroke = new SolidColorBrush( Colors.Blue );

l.Appearance.PointMark.StrokeThickness = 1;

l.Appearance.PointMark.Fill = new SolidColorBrush( Colors.Transparent );

l.Appearance.PointMark.Shape = MarkerShape.Diamond;

this.radChart.DefaultSeriesDefinition = l;

but none of them worked really out.
The first example works until the selected points are deselected. After deselection the style is the default
style and not my applied one. (My next attempt is to set the style again, after the points are deselected.)

Do you have any idea?

kind regards
Hubert
